Deep V and K band photometry of the host galaxy of Haro 11
2009 (English)Conference paper (Other (popular science, discussion, etc.))
Previous studies of the host galaxy of Haro 11 have suggested an extreme red color of V-K=4.2+-0.8 which cannot be reconciled with any normal stellar population of reasonable metallicity. We present the deepest V and K band data to date of the blue compact galaxy (BCG) Haro 11 and derive a new V-K color for the host. Our new data suggest a much more modest value of V-K=2.3+-0.2, which is in the same range as V-K colors measured for several other BCGs. The new Haro 11 color is not abnormally red and can be attributed to an old metal-poor stellar population with a Salpeter initial mass function.
